D33-D43Primary Range
Benign and uncertain behavior neoplasms of the brain and central nervous system
This range includes codes for benign, uncertain, and unspecified behavior neoplasms of the brain, which are primary for coding brain lesions.
Secondary malignant neoplasm of brain and cerebral meninges
This range is used for coding metastatic brain lesions, which are secondary to primary cancers elsewhere in the body.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D33.0 | Benign neoplasm of brain, supratentorial | Use when imaging confirms a benign lesion in the supratentorial region. |
|
| C79.31 | Secondary malignant neoplasm of brain | Use when a brain lesion is identified as metastatic from a primary cancer. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for brain lesion
Decision Criteria
clinical Criteria
- MRI confirms benign characteristics without enhancement.
Applicable To
- Benign supratentorial brain tumor
Excludes
- Malignant neoplasm of brain (C71.-)
Clinical Validation Requirements
- MRI showing a well-circumscribed mass in the supratentorial region
- No enhancement on contrast imaging
Code-Specific Risks
- Risk of using unspecified codes when specific location is known.
Coding Notes
- Ensure documentation specifies the supratentorial location to avoid unspecified coding.
C79.31 - Secondary malignant neoplasm of brain
Use when a brain lesion is identified as metastatic from a primary cancer.
Applicable To
- Metastatic brain tumor
Excludes
- Primary malignant neoplasm of brain (C71.-)
Clinical Validation Requirements
- Pathology report confirming metastasis
- Imaging showing new brain lesion in a patient with known primary cancer
Coding Notes
Always sequence primary cancer before C79.31.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Brain Lesion to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D33.0.
Impact
Clinical: Inaccurate representation of patient's cancer status., Regulatory: Potential audit risk for incomplete coding., Financial: Loss of reimbursement for unlinked primary cancer.
Mitigation Strategy
Always verify primary cancer documentation before coding., Use checklists for metastatic coding.
Impact
Reimbursement: May lead to lower DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines requiring specificity., Data Quality: Decreases the accuracy of clinical data.
Mitigation Strategy
Use specific codes such as D33.0 or D33.1 when location is documented.
Impact
Risk of coding metastatic lesions without primary cancer.
Mitigation Strategy
Implement a verification process for primary cancer documentation.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
